Note: comparisons to recent years other than 2012, particularly for primetime viewing, are apples-to-oranges. 2012 was the last time the U.S. Open was played on the west coast and also the last time the open was telecast during primetime.

Versus the 2012 telecast this year’s second round looks to be down a bit — 1.97 million viewer per minute average for the whole day versus 2.909 million in 2012. It’s even down versus 2013’s second round (which was on the east coast and did not involve any primetime coverage) and averaged 2.095 million viewers.
